Many of those heaters use a cheap "mono bearing" motor and can be rescued in most cases by punching or drilling a small hole in the rear cover and adding lube oil. The oil felt gets dry and doesn't lube the shaft properly.

You may have to spin the motor manually to get a start but once the oil gets to the shaft it will spin like a new one.
